Stratigraphic Architecture
Stratigraphic architecture records the interaction of sedimentary processes and associated morphodynamic changes of the system, which is highly variable in time and space.
Point bar architecture
Point bar of the river formed in the fluvial-tidal transition typically consists of inclined heterolithic stratification (IHS). Sandy layer represents high river discharge and muddy layer reflects low flow stage when tidal influence becomes notable. We study the architecture of IHS formed in a variety of environmental setting.
Tidal flat architecture
Tidal flats have evolved in response to relative sea-level change that controlled the relative significance between tidal and wave processes, and sediment supply. We study the stratigraphic record preserved in the Korean tidal system to unveil the dominant processes and spatial variability of the architecture.
Quaternary stratigraphy
Coastal areas host past record of sedimentation in response to changes in physical processes, sea-level changes and sediment supply during the late Quaternary. Multidisciplinary dataset such as long cores, seismic profiles, age-dates are used to unravel the evolution of the sedimentary record.
